A Coastal Flood Warning is in effect for the Upper Keys. A Coastal Flood Advisory is in effect for the Lower and Middle Keys. In the Upper Keys, numerous roads may be closed. Low lying property including homes, businesses and some critical infrastructure will be inundated. Some shoreline erosion will occur. In the Lower and Middle Keys, saltwater flooding of low elevation streets and lots is expected. Some storm drains will overflow, and some seawalls and docks will be overtopped. Boaters should expect less clearance under fixed bridges. Motorists should remember that persistent puddles around the times of high tide are almost certain to contain a mix of saltwater. For more information on coastal flooding, refer to www.weather.gov/key/coastal_flooding

Above normal rain/thunder chances will continue through the next several days. At the same time, we will have to contend with King Tides, resulting in saltwater flooding of low elevation streets and lots during times of high tide. If heavy rainfall should occur around the times of high tide, we could see worsen flooding conditions.
